DMPlexSetAdjacencyUser - Define adjacency in the mesh using a user-provided callback

Input Parameters:

+ dm - The DM object

. user - The user callback, may be NULL (to clear the callback)

- ctx - context for callback evaluation, may be NULL

Level: advanced

Notes:

The caller of DMPlexGetAdjacency may need to arrange that a large enough array is available for the adjacency.

Any setting here overrides other configuration of DMPlex adjacency determination.

1555

Input Parameter:

1556

+ dm - The original DMPlex object

1557

- overlap - The overlap of partitions, 0 is the default

1558

1559

Output Parameter:

+ sf - The PetscSF used for point distribution, or NULL if not needed

1561

- dmParallel - The distributed DMPlex object

1562

1563

Note: If the mesh was not distributed, the output dmParallel will be NULL.
